> Key: MESOS-6246
> URL: https://issues.apache.org/jira/browse/MESOS-6246
> Project: Mesos
> Issue Type: Bug
> Components: libprocess
> Affects Versions: 0.27.3, 0.28.2, 1.0.1
> Reporter: Joseph Wu
> Assignee: Joseph Wu
> Labels: libprocess, mesosphere
>
> Noticed this while inspecting nearby code for potential races.
> Normally, when a libprocess actor (the "linkee") links to a remote process,
> it does the following:
> 1) Create a socket.
> 2) Connect to the remote process (asynchronous).
> 3) Check the connection succeeded.
> If (2) or (3) fail, the linkee will receive a {{ExitedEvent}}, which
> indicates that the link broke. In case (1) fails, there is no
> {{ExitedEvent}}:
